Title: Method for selecting phs data communication means
Inventor: NAKAJIMA YASUO
IPC: H04W48/16
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a data communication unit that can reduce a time until a communication channel is set up. SOLUTION: In the case of making a speech request from a PHS terminal set 10 of a mobile station side to a PHS terminal set 15 at a fixed station side, the PHS terminal 10 of the mobile station side derides a transceiver communication mode or a public communication mode on the basis of position information of its own terminal and makes a call. In the case of making the call in the transceiver communication mode, the PHS terminal 10 of the mobile station side directly makes a call to the PHS terminal 15 at the fixed station side. Furthermore, in the case of making the call in the public communication mode, the PHS terminal set 10 of the mobile station side makes a call to the PHS terminal set 15 at the fixed station side via a facility 75 of a communication enterprise.

Abstract: PURPOSE:To conduct a fast propagation test equivalently even by a relatively slow LSI tester by shifting the phase of a clock signal which is supplied from the LSI tester to clock input terminals of respective FFs of an LSI. CONSTITUTION:This test system uses the LSI tester which outputs the clock signal at constant cycle time and outputs clock signals which are in optional phase and have optional pulse widths in respective cycles, and the clock signal which is supplied from the LSI tester to clock input terminals of respective FFs I - IV of the LSI 1 is shifted in phase to obtain a clock which is narrowed down in interval in every cycle so that positions of intervals to be narrowed down for 1st and 2nd times are different. For example, the clock is narrowed down in interval between an even and an odd cycle for the 1st time and between an odd and an even cycle for the 2nd time. Those two kinds of clocks are used and the LSI is tested twice, so a fast test is conducted by the relatively slow LSI tester as well as a fast LSI tester.

Filed: 1987-12-08
Abstract: PURPOSE:To measure the harmonic distortion of a speaker with few data in a short time by converting a sound pressure signal into an electric signal by a microphone, converting this signal into a digital signal by an A/D converter, storing it and executing a prescribed interpolation. CONSTITUTION:As the sine wave of a frequency (f) is discreetly changed as an input signal within the measuring range, it is impressed on the speaker, an output sound pressure from the speaker is converted into the electric signal by the microphone, after that, it is made into a digital signal by an A/D conversion and data for one period of each frequency are cut out. After that, by the interpolation in each frequency, a sampling time DELTAt is changed, that is made into the data of an N point (N is the number of data of one period after the interpolation) to satisfy DELTAt*N=1/f and the harmonic distortion is obtained by a Fourier series approximation. Thus, it is sufficient to fetch the data of at least one period and a fetching time becomes much shorter in comparison with the case of using an FFT argorithm by an FFT analyzer.
